Percentage Growth Calculator
Calculate percentage growth between a starting value and an ending value. The calculator shows the absolute growth and percentage growth so you can quickly measure how much a value has changed.
Enter a starting value and an ending value to calculate the percentage growth.
How to Calculate Percentage Growth
- Subtract the starting value from the ending value.
- Divide the result by the starting value.
- Multiply by 100 to express it as a percentage.
Percentage Growth Formula
Percentage Growth = ((Ending Value − Starting Value) ÷ Starting Value) × 100
Percentage Growth Between Two Numbers
To find the percentage growth between any two numbers, treat the first as the starting value and the second as the ending value, then apply the formula above. The result tells you how much larger (or smaller) the ending value is, relative to the starting value.
Percentage Growth Example
Starting value = 100, Ending value = 150. Growth = 150 − 100 = 50. Percentage growth = 50 ÷ 100 × 100 = 50%.
Percentage Growth vs Percentage Increase
Percentage growth and can describe the same underlying calculation when the starting value is treated as the reference point. In practice, "growth" is more commonly used to describe changes measured over a period of time — such as revenue, population, or website traffic — while "percentage increase" is a more general term that can apply to any comparison between two values.
Year-over-Year Growth
Year-over-year (YoY) growth compares a current period with the corresponding period from the previous year, using the same formula:
Year-over-Year Growth = ((Current Period − Previous Period) ÷ Previous Period) × 100
For example, if quarterly revenue was $80,000 a year ago and is $92,000 this quarter, YoY growth = (92,000 − 80,000) ÷ 80,000 × 100 = 15%.
